The pipe reportedly appeared to surface recently and was witnessed releasing a dark plume into the ocean, causing a detectable odor in the area. Two regular beachgoers, 15-year-olds Apiranya and Kanokporn, noted they first saw the pipe over two months ago, believing it to be new. Questions have arisen regarding its origin and the lack of oversight for the untreated wastewater flow into the sea.

Local residents and online communities are urging responsible agencies, including Pattaya City and Na Jomtien officials, to investigate the situation. There are calls for the intervention by the Department of Marine and Coastal Resources alongside other environmental bodies. These groups are tasked with determining which office is responsible for the management and maintenance of the area.

Community voices have highlighted the necessity of repairing the drainage system and redirecting the wastewater appropriately to maintain seawater quality. Concerns have also been voiced about the potential impact on marine life, public health, and the tourism industry in Pattaya. Additionally, the presence of the exposed pipe is seen as a potential hazard, particularly for children and teenagers who might explore it.

Nothing to see here. Pattaya and Jomtien have been pumping raw <deleted> into the Gulf for decades. Can "clean up" the city but not deal with their own <deleted>. Disgraceful and disgusting that no one can swim in the ocean due to fear of catching diseases.

BTW, if "clean up" means driving prostitution underground, that leaves women in the industry even more subject to risk and exploitation.
